oULrIvAron.

To all whom/it may concern: l

1 Be it known that I, SHERMAN OVERALL, a citizen of; the United States, residing at Mount Vernon, in the county of Lawrence and State of Missouri, have invented certain newand useful Improvements in 1 Cultivators and I do declare the following to be a full,

- clear, and exact description of the invention,

, is full grown.

such-as will enableothers skilled in the art to which it appertains to make and use the same.- i, 1

My invention relatesto. improvements in agricultural implements, and more particu -t larly to cultivators.

It is a well-known fact thatthe wheel cultivators in use/today arenot applicable for the purpose of cultivating corn ornoth'er cropsyafter they'have reached a height of approximately two or three feet. It is also a wellknown fact that corn, in particular, is greatly assistedin its growth the'process of cultivating the same iscontinued until it The primary object of my invention, therefore, is tof provide a c ultivator of the herein described character which is con structed in'such a manner as to render it ap- 1 plicab'le for cultivating full grown corn. To

this end, I employ an arched axle, an

arched doubletree, a pair of tongues, and an arched neck yoke ,connecting the forward ends thereof.

A secondary obj ect' of the invention isto form a simple and efficient brace for the arched doubletree, which will allow the same to swing upon a pivot and yet will effectually perform its function.

Still another object is to connect the neck yoke to the forward'end sof the tongues, in" such a manneras to cause the same to read-' ily equalize any back dr'aft applied to the I opposite ends thereof, by the draft animals.

" With theiabove objects in view, the llll vention resides in 'certain' novel features of construction and combination" herein described and claimed and shown inthe drawings whereinf 7 Figure 1, is aside elevation of my improved cultivator; Fig. 2' is a plan view" thereof; Fig, 3is a,vertical section on'the line 3-3 of Fig. 1; the cultivator being omitted; Fig. 4 is a similar view on the line H of Fig. 1; and Fig. 5 is a detail vertical section taken on the line 5"5 of Fig. 2; and Fig. 6 is a detail perspective view ofa p 11; tion of the neck yoke.

p Specification of Letters Patent. Patentgd Sept, 22, 1914:. Application filed April 16, 1914. Serial No. 832,296.

In the accompanying drawings, I have shown my, improved cultivator as comprising, in general, a pa1r of supporting wheels 1, an. arched axle 2, an arched doubletree 3, a palruof tongues 4, an arched neck yoke 5,

and a' plurality of cultivators 6. The wheels 1 may be of any suitable formation and are revolubly mounted in any "appropriate manner upon horlzontal portions 7 of the arched axle 2-, said horizontal portions being connected by an arch 8, which, as clearly shown in Fig. 3, is of suiiicient height to allow its upright portions to straddle rows of full Projecting forwardly from the upper end of the arch 8 is a bar 9 which is preferably secured rigidly to said arch by'aclamp 10. This bar 9 is employed for the purpose of forming a pivotal support for the arched doubletree 3, the latter comprising horizontal portions 11, to which the swingletrees 12 are loosely connected, upright portions 18 rising from the inner ends of the portions 11 and a cross bar 1a which rigidly connects the upper ends of said bars 13. The cross bar l l is pivoted at its center, beneath the forward end ofthe bar 9, by means of a suitable pivot bolt 15. By mounting the doubletree 3*in this manner, it will be seen that the draftwill be equalized upon each swingle- ,tree 12. It will also be seen that said dou bletree must be braced and that no braces canextend across the spacebetweenthe upright portions of either the axle 2 or said doubletree. It is tobe" further'noted that the'ends of the doubletree could notbe rigidly braced to the axle, since this would prevent any rocking of said doubletree around its pivot 15. It therefore becomes expedient to provide the bracing means now tobe described.

Projecting rearwardly from the opposite ends of the cross bar 14, is a curved segment '16, which, as clearly shown in Fig. 5, overlies the bar?) and slides loosely beneath'a yoke 17, fixed tosaid bar. The 'oppositeends of the segment 16 are rigidly secured to the horizontal ,baryl, as indicated" at'18. Theprovision of the segment 16 and itsniounting'would bracethe doubletree 3 to an ap- Qpifeciableext'ent, but I deem it advisable to provide brace bars 19 which arerigidly se cured at their lower ends to the horizontal portions 11 of said doublet'ree, while their upper ends are secured to the segment 16 at pointsin rear of the forward ends thereof. Thus, it will be seen that I have produced a simple and effective brace for the d'oubletree 3 which will effectually perform its function and yet will allow said doubletree to rockupon its pivot. a

The tongues 4: are preferably secured at their rear ends to the upright side barsrof the arch :8, while their forward fends are from the inner sides ofthe yokes 20, and

per sides of the tongues 4. g structio-n when either end of the yoke 5 spaceda distance equal, to the width of said arch. The upper side of each forward end of. the tongues of is provided with a yoke 20, saidyoke's being provided for the reception of horizontal portions 21 of the neck yoke '5, theupri ght portions 22 thereof forming the side bars of the arch. By reference to Fig. 2, it will be seen thatthe outer sides of the bars 22 are spaced a slightdistance by reference to Fig. 1-, it will beseen that the horizontal portions 21 of the yoke .5,

are allow-ed aslight amount of -longitudinalmovement between the yokes 20 and the up- By this c0n- 1s pulled rcarwardly, the opposite end thereof will move forwardly-andthus the 'backdraft on. said yoke will be equalized, The porv tions1-21 arepreferably flattened as shown at 23, said flattened portions engaging the yokes 20 and the upper faces of the tongues 4, and "thus preventing the yoke o from tipiping forwardly or rearwardly. The

arched air-1e 2, the doubletree 3, and the neck "yoke 5}, may each be formed of a single piece f t l, or if found advisable, they any manner whatsoever.
